She looks older because she is using a different hair do. Her previous ones were more youthful. The new one is more mature and befitting of a young Roman matron with children, in this case Felix’s daughter.

I like how she has correctly interpreted the seer’s prediction. She has followed him and has lost most of her fortune, but she has to realize that the other option was to remain entombed for eternity with her wealth.

Now she has to look to the future and grab it with both hands and fight for it.
